FEED-*WATER HEATER;

SPECIFICATION forming part Of Letters Patent N0. 724,413, dated.ll/Iar'cli 31, 1903. Application filed December 20, 1902. Serial No.135,987. (No model.)

To all whom it may concern:

Be it known that LFRANK C.TRAUER, a citizen of the United States,residing at Heizer,'

in the county of Barton and State of Kansas, have invented new anduseful Improvements in Feed-Water Heaters,- of which the follow- .ing isa specification.

My invention relates to improvements in feedwater heaters forsteam-boilers, and more particularly pertains to that class used onlocomotives.

The object of my invention is to provide a device of the characterdescribed in which the waste heat and smoke passing through thesmoke-box and the smoke-stack is more efiectively used in heating thewater before it is fed into the boiler and saving fuel and also allowinga greater steam-pressure to be kept in the boiler with the leastpossible amount of fuel.

Another object of my invention is to provide a device of the characterdescribed which is provided with means for cleaning the same and alsomeans for drawing the water therefrom for the purpose of preventing thesame from freezing when the engine is not in use.

In the accompanying drawings, Figure 1 is a perspective view of alocomotive with my device attached thereto. Fig. 2 is a transversesectional view. Fig. 3 is a front view of a locomotive. Fig. 4 is adetached perspective view of the tank, showing the opening through whichthe smoke-stack passes.

Referring now to the drawings, A represents the ordinary tubular boilerused on 10- comotives now in use, and B is the smokebox carried by theforward end thereof and through which passes all of the smoke and gasesfrom the fire-pot or furnace. Extending in the usual manner from theupper portion of said smoke-box is the smoke-stack C, which conveys thesmoke and gases upward and causes a greater draft within the grate orfire-box.

The receptacle or tankD is oblong and extends transverse the smoke-box,and the upper portion is provided with an enlarged opening (I, throughwhich the smoke-stackO passes, and surrounding the same is an upwardlyextending flange d, by means of which it can be secured to thesmoke-stack by rivets or bolts. The bottom of the tank D is formed bytheupper portion of the smoke-box B, and surrounding the entire loweredge of said tank D is a flange d. Passinglthrough said flange and thesmoke-box are bolts or rivets, by means of which the tank is heldthereon and by means of which a water-tight connection is formed. Bythis construction it will be seen that the bottom of the tank is formedby the upper portion.

The ends of said receptacle or tank D, adjacent the lower portion, areprovided with stopcocks F and F, of any desired construction, which willallow the water therein to be drawn off for the purpose of preventing itfrom freezing when the engine is not being used. The forward side-ofsaid receptacle or tank D is provided with openings G and G, adjacentthe ends, through which sediment may be readily removed. Surroundingsaid openings are outwardly-extending bolts H, which pass through theplates I and I,which cover said openings, and between said plates andthe tank are packings, and screwed upon the ends of the bolts H are nutsH, which are adapted to force the plates I and I upward, and thus, makea water-tight connection. The upper portion of the receptacle or tank Dis provided with an opening J ,through which the water is injected tofill the tank and boiler when it has been drawn ofi for the purpose ofpreventing the freezing thereof, as the water cannot be forced throughthe pipe E before the steam has been generated in the boiler, as themeans carried by the pipe E for forcing water into the tank is driven bythe engine. Connected to the upper portion of the opposite end to whichthe supply-pipe is attached is a pipe K, which extends downward and runsalong the boiler and enters the same about midway its length, so thatthe heated water will enter the con ter of the boiler and evenlydistribute itself V smoke-stack carried by said box, of a feedwaterheater comprising an elongated tank extending transverse the boiler andhaving a central opening therein adapted to receive the smoke-stack, aflange surrounding said opening and secured to the smoke-stack, and aflange surrounding the lower edge of said tank and secured to the saidsmoke-box.

2. The combination with a cylindrical boiler having at one end asmoke-box, an upwardly-extending smoke-stack carried thereby, of afeed-water heater comprising a rectangular tank having, a curved openbottom adapted to rest upon said smoke-box, a flange surrounding saidopen bottom and secured to the smoke-box, the said tank having anopening in its top adapted to .receive the smoke-stack, and a flangesurrounding said opening and secured to the smoke-stack.

3. The combination with a boiler having at one end a smoke-box and anupwardly-extending smoke-stack, of a feed-water heater comprising anelongated tank, extending transverse the boiler and supported therebyand surrounding the smoke-stack, a supplypipe in communication with thelower portion of one end of said tank, a discharge-pipe in communicationwith the upper portion of the opposite end and connected to the boiler,a check-valve carried by the pipe intermediate the boiler and tank, saidtank having cleanout openings carried by the forward side, and cookscarried by the lower portion of each end, substantially as described.

4. The combination with a boiler having at one end a smoke-box and anupwardly-extending smoke-stack, of a feed-water heater comprising anelongated tank extending transverse the boiler and supported thereby andsurrounding the smoke-stack, a supplypipe in communication with thelower portion of one end of said tank, a discharge-pipe in communicationwith the upper portion of the opposite end and connected to the boiler,a check-valve carried by the discharge-pipe intermediate the tank andboiler, said tank having clean-out openings carried by the forward side,cocks carried by the lower portion of each end of said tank, and theupper portion of said tank having a filling-opening, substantially asdescribed.

5. The combination with a boiler having at one end a smoke-box and anupwardly-extending smoke-stack, of a feed-water heater comprising anelongated tank extending transverse the smoke-box and having an open ingin its upper side through which the smokestack passes, a flangesurrounding said opening and secured to said smoke-stack, and the bottomof said tank formed by the upper portion of the smoke-box, and a flangesurrounding the lower portion of the tank and'bolted to the smoke-box,substantially as described.

6. The combination with a boiler having at one end a smoke-box and anupwardly-extending smoke-stack, of a feed-water heater comprising anelongated tank extending transverse the boiler and resting upon the sameand surrounding the smoke stack, flanges carried by said tank andsecured to the boiler and smoke-stack, a supply-pipein communicationwith the lower portion of one end of said tank, a discharge-pipe incommunication with the upper portion of the opposite end and connectedto the boiler, a checkvalve carried by the pipe intermediate the boilerand the tank, said tank having cleanout openings carried by the forwardside, and cooks carried by the lower portion of each end.

In testimony whereof I have hereunto set my hand in the presence of twosubscribing witnesses.

FRANK C. TRAUER.
